Do
you need to run the generator when you use the air conditioning?
If so how is it affecting the mileage?

We
need to have the generator on to use the air conditioning.
The generator burns about 1/2 gallon per hour and that equals
roughly about 1 1/2 nm an hour that we loose. To give you
an example, on long runs, say over 2300nm, we would most likely
not run the air to increase our range.
